IMPROVEMENT IN BlLGE-PUMPS.

Specification forming part of Letters Patent No. 172,900, dated February 1, 1876; application filed f December 8, 1875. l i

Improvement in Bilge-Pumps 5 and I do hereby" declare that the following is a full,'clear,

and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specication, and tothe letters and figures of reference marked thereon.

Figure 1 `of the drawings is a representation of a top view of my pump. Fig. 2 is a transverse vertical section, made through the dotted lines c b.

My invention has relation to pumps, and while it is adapted for general use, it is more particularly calculated for al bilge-pump for use on board ships. It consists in the novel construction andarrangement of devices intended to serve as al1 efcient means for the purpose named.

Referring to the accompanying drawing, A.

represents the main mast ot' a ship, and B the tife'rail surrounding the same.` C C indicate two beveled cog balancewheels secured to the shaft D, the ends of which revolve .in

suitable journals constructed on the top of the rife-rail. These balance-wheels G C are operated by means of force applied Vto the cranks c c. Fitting into the beveled cogs on the inner rims of the wheels G C, and operated by them, are the smaller beveled cog-wheels c c, which are supported by uprights b b, through the tops of which pass the axles ot' the wheels c c. Attached to the outer ends of the axles of the wheels c c, or the ends nearest ythe pumps, are the elbow-cranks d d, which operv ate in the slots e e of the working-beam E.

The ends of the working-beam are constructed to rise and fall in suitable grooves in the supports n n. To the under side of the workingbeam E the piston-rods f j' of the pumps g g are attached. EA represents the basin into which the water rises, and h h the pipes by which it is conveyed away.

lt will now be 'readily seen that by turning the cranks a a, attached to the ends of the shaft D,motion will be communicated'through them to the balance-wheels C C and 0,0, and

that the revolution of the elbowlcanks d d in the slots e e in thel working-beam E will give to the working-beam, and to the pistonrods attached to it, a regular vertical movement.

In the event that it should be found desirable to register the number of strokes of the working-beam, caused lby a certain number of revolutions of the balance-wheels, screwthreads are turned on theshaft D, which cause to revolve the'reel m,supported by, and revolving upon, two, uprghts, in the tops of which suitable `journals are made to fit the axis of the reel. On one side of the reel a pintle, p, is placed, which, as the reel revolves,

comes in contact with an upright spring-pendulum7 r, causing it to strike the bell s. On a ship `of fifteen lhundred tons register, for example, is required a pump one revolution of the balancewheels ot' which produces eight vertical movements of the working-beam. If the register be'constructed to note when one hundred revolutions of the balance-wheelsA have been accomplished, it is easilyseen how many strokes of the piston-rods have been made during the same time.

This pumpcan be adapted for use on all kinds of vessels. By making the balance-v wheels larger or smaller, or by placing the cogs vnearer or more remote from the center of .motion, any number of strokes may be obtained.

It is claimed that this pump is better adapted for a bilge-pump than anyother now in use. It is simple in its construction, ei'ectual in its operation, and can be operated by a comparatively small amount of power.

The water thrown by this pump is large in quantity proportioned to the amount of power required to operate.I This is its great advantage as a bilge-pump, and as a pump for general use, a large amount of water can be thrown in a comparatively short time. It is, in short, a time-saving and a labocsaving apparatus, both on shipboard and for general use.`

What I. claim as my invention, and desire to secure by Letters Patent, is-' l. In a bilgepump, the vslotted workingbeam E, operated by means'of the bala-nce-` wheels C 0, and the beveled cog-wheels c c,
